Nvidia Gpu Boost 3 0
It is not thermal throttling.
Nvidia gpu boost 3 0. This dynamic clock speed adjustment is controlled by gpu boost which monitors a raft of data and makes real time changes to speeds and voltages several times per second maximizing performance in each and every application. Prior to gpu boost 3 0 the only way to overclock was to adjust the clockspeed for all voltage points by the same amount at the same time or in nvidia s gpu boost 3 0 vernacular a fixed. With gpu boost 3 0 nvidia now offers custom per voltage point frequency offsets allowing the gpu to maximize the headroom beyond a fixed frequency offset it is a natural evolution of gpu boost 2 0 while the latter could already dynamically vary the boost speed. The stepping down of core clocks is merely the card managing the above factors against max clock speed.
Gpu boost continuously monitors power and temperatures helping your gpu use every bit of performance without exceeding safety or comfort limits. Think of gpu boost 3 0 as a self overclock a technology where a pascal gpu will depending on available power voltage and thermal headroom push its own core clock way higher than is officially advertised.
